Structural characteristics of flow units in Svalbard valley glaciers and their utility for investigating ice-dynamic changes over centennial timescales

open access: yesJournal of Glaciology
The aim of this paper is to characterise the internal structures and ice-flow history of representative valley glaciers in Svalbard and infer from them dynamic changes over centennial timescales.

Foliations by planes

open access: yesTopology, 1968
AbstractIn this paper we study some properties of three dimensional manifolds foliated by planes. The main result is Theorem 3, which states the three dimensional torus is the only closed three manifold which admits a C2 foliation by planes; the author obtained this result in collaboration with J. Sondow. We show how this result gives information about

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Rapid evolution of complex limit cycles [PDF]

open access: yes, 2009
The current article studies certain problems related to complex cycles of holomorphic foliations with singularities in the complex plane. We focus on the case when polynomial differential one-form gives rise to a foliation by Riemann surfaces.

Enlargeability, foliations, and positive scalar curvature

open access: yes, 2017
We extend the deep and important results of Lichnerowicz, Connes, and Gromov-Lawson which relate geometry and characteristic numbers to the existence and non-existence of metrics of positive scalar curvature (PSC).

Dimension Distortion by Sobolev Mappings in Foliated Metric Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2013
We quantify the extent to which a supercritical Sobolev mapping can increase the dimension of subsets of its domain, in the setting of metric measure spaces supporting a Poincaré inequality. We show that the set of mappings that distort the dimensions of

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Geometric properties of the Minkowski operator

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
This article is about Minkowski difference of sets, which is one of the Minkowski operators. The necessary and sufficient conditions for the existence of the Minkowski difference of given regular polygons in the plane were derived. The method of finding

Dicritical logarithmic foliations [PDF]

open access: yesPublicacions Matemàtiques, 2006
We show the existence of weak logarithmic models for any (dicritical or not) holomorphic foliation F of (C2 , 0) without saddlenodes in its desingularization. The models are written in terms of a representative set of separatrices, whose equisingularity types are controlled by the Milnor number of the foliation.
